IMPROVEMENT IN INJECTORS.

Specification forming part of Letters Patent No. 91,205, dated June 15, 1869. I

To whom 'it may concern:

Be it known that we, ALBERT J. BLAKsLEE and GARNER G. WILLIAMS, of Du Quoin, in the county of Perry and State of Illinois, have invented a new and useful Improvement in Steam-Siphons; and We do declare that the following is a true and accurate description thereof, reference being had to the accompan ying drawings, and to the letters of reference marked thereon, and being a part of this speciiication. i Y

This device relates to that class of inventions known as steam-siphons 5 and consists of a steam-pipe, delivery-pipe, and suctionpipe, all terminating in a T or globe shaped connection or socket, and operating for the purpose of elevating and forcing a column of water hy the action of a jet of steam impinging thereon; also, in the employment of a series of two or more steam-jets in the same column, for the purposes hereinaftery described.

In the drawings, which are a vertical section ot' our device, A represents a T-shaped socket, into the branch ot which enters the suction-pipe B.

0 is a steampipe entering thei lower arm of the T, and extending nearly through it and across the mouth of the suction-pipe B, and terminating in or near the mouth of the funnel a, formed in the opposite end of the arm of the T, leaving only space enough between the end of the steam-pipe C and the Walls of the funnel a for the passage of but sufficient water to till the contracted orice d, so that the pressure of the steam will be at once exerted on the small column of water in the contracted pipe.

D is the delivery-pipe, having a contracted or smaller opening, d, issuing from the funnel a., and terminating in the larger diameter of the delivery pipe. This contracted pipe d should be of sufiicient length to retain the body of water passing through it in close contact with the jet of steam until allthe steam entering with it shall be condensedl l It is not necessary to employ a fu nel, a, at the end of the delivery-pipe, as sho .'11, unless the contracted pipe d 'is of the same or less diameter than the steam-pipe G.

The force of the steam issuin steam-pipe C expels the air g lfrom the through the contracted pipe d, and its place is supplied by Water through the suction-pipe B by the pressure of the atmosphere exerted thereon. When the steam and water come in contact at the mouth of the steam-pipe, a portion of the steam is condensed.

It is evident that all the steam will not be condensed at the instant ot' leaving the steampipe, but only the exterior of the jet, while the central or interior part will not be condensed until it has passed some distance into the contracted pipe; hence the necessity et' continuing the contracted opening d until the nal condensation of the jet of steam is ei'- fected, and thus utilize the entire force of the steam.

If from any cause the power of the siphon is inadequate to force the water to the end ot' the delivery-pipe, at the proper point in thel delivery-pipe we insert another steamjet simi lar in construction to that already described except that the steam-pipe C' enters the branch of the T-shaped socket A', while its lowefV arm forms the suction.

The steam-pipe C' is curved in the socket. so as to present its orifice toward, and discharge the steam into, the contracted passage d! 0f the delivery-pipe D', and in the line 01 the ow of water, and force the same through the delivery-pipe D', in the manner already described.

It will clearly be seen that, the first siphon having raised and forced the water to a certain height or distance in the delivery-pipe, this second jet will then accelerate its passage along to the outlet E of the delivery-pipe D', or, it' necessary, others in sufficient number may be inserted and employed to eiect the purpose.

F is a stand-pipe, open at the top, and rising above the point of linal discharge, and al lowing the steam to escape freely until the vacuum is formed in the T below and the suction established, when the Water, rising in the delivery-pipe D' until it reaches the horizontal outlet E, will pass into and be discharged from the same by its own gravity.

If from any cause the suction-pipe should be obstructed, the caps G and G' may be screwed onto the ends ot' the stand-pipe and outlet and the whole force of tl ie steam be exerted in the suction-pipe to remove the ob- E, the stand-pipe F, and the caps G G,when strvelgiom l d d constructed and arranged as above set forth.
